This website is currently tuned to provide information on my research to students who are considering joining us, namely, students seeking for PhD guidance or considering our Integrated MSc-PhD Programme. Professional researchers may find me on the ResearchGate. For broader outreach programmes, refer to our centre on social media: you can find the links at the bottom. Of course, anyone is free to enjoy the contents here as he/she likes, for good use.
In the beginning, I wanted to find the complete theory of quantum gravity. As such, I was naturally led to study string theory. During my MSc and PhD at Osaka University, I was trained in High Energy Physics - Theory.
Recently, I am also interested in testing theoretical models with experimental data. Traditional experimental facilities in high energy physics are particle colliders. However, the progress of human technology in this direction is not as fast as we wish. Therefore, I seek data from extremely high energy states in the early universe - their imprints in cosmological observations.
